OTP-KIV return on new Embraer 190. The flight was quick and the little snack was more than ok. Flight Attendants were only interested in some passengers and didn't really care at all for the others. I felt sort of unsafe as no particular attention was brought to passengers calling on cellphone or using electronic devices during take off and landing! My return trip was with the small Embraer 120 for KIV-OTP flight. This very old little plane of 30 seats only was comfy and I felt safe. The single cabin crew who was working was smiling kind and hospitality was great. We left and arrived on time.
